Answer 3

ok for the mean, you have to add up all the numbers, then divide by the total number of numbers. the sum of them would equal 40. since theres values given, divide by 10 to get 4. 4 is your mean. to find the deviation, you have to find the difference of each number given and the mean. so for all the 3's, itd be 1. for the 4's, its 0. for the 5's, its 1 and for the 6, its 2. so now, add 1,1,1,1,0,0,0,1,1,and 2 which equals 8. divide that number by 10, which gives you .8. thats your answer!
